利用VisualStudio白盒測試入門

現在越來越多的軟體開發使用白盒測試了，C++有CppUnit，.Net有NUnit， 在VisualStudio中也給我們提供了一套測試架構，但是該測試架構似乎只有在VS某幾個版本才有。

    那麼VisualStudio有哪些版本呢？以VisualStudio2005來看，他有些什麼版本呢？各個版本有些什麼區別呢？

    請參考網頁：

    下表是從該網頁中拷貝出來的。即Visual Studio 2005產品線一覽圖。

  簡單來說，我們可以歸納一下：
  Express---試用版
  Pro---全稱是Visual Studio 2005 Professional Edition，是適合小規模使用的版本，授權8-10個人左右。
  Std---全稱是Visual Studio Standard Edition，也是授權版本，比Pro多一些；
  VSTO---Visual Studio 2005 Tools for the Microsoft Office System，對office系列產品進行開發；
  VSTS---Visual Studio 2005 Team System，也是針對軟體開發的各個層次最全面的一個版本
   可以看到，這幾個版本中，只有VSTS有Unit Test的功能。所以要想利用VisualStudio來做白盒測試，必須安裝VSTS，其他版本都沒有。

    安裝完VSTS後，開始寫白盒測試代碼吧。一步一步做吧：

    1.建立測試專案

    2.在產生的UnitTest1.cs檔案中修改代碼，：

    這樣我們寫了2個測試方法TestMethod1(),TestMethod2(); 分別讓其通過和不通過。

    3.在實際的項目中，測試方法（Test Method）會非常多，為了方便管理，會建一些測試清單（Test List），：

    4.忘了說了，Test Manager這個工作區是怎麼顯示出來的了。

先在菜單 View – Toolbars - Test Tools 中選中，讓其顯示測試載入器條，然後在測試載入器條上點擊Test Manager按鈕，請看。

    然後呢，如所示，先在Test Manager中選中要啟動並執行Test Method，然後點擊用紅框標出的按鈕，就可以運行選中的Test Method了。
    運行完之後，開啟Test Result面板，就能看到啟動並執行結果了，可以看到，我們寫的Test Method，一個Passed了，一個Failed了。
    呵呵，白盒測試入門就是這麼簡單。
